Hi, Thank you for posting your query. If a person has tumors in both brain and lung, it is most probably starting in one of those areas, and spreading to the other area. In this case, the most likely possibility is a primary cancer of the lung, which has spread to the brain, a process called as metastases. You should consult a medical oncologist for this, as the treatment involves using chemotherapy. In some cases, radiation therapy may be required, for which he may be referred to radiation oncologist. This advice is absolutely free. I hope it helps. Please get back if you require any additional information.
